The second lamella originates opposite from the first lamella. The third lamella supports the third vane, which is located more distally and lies perpendicular to the other two vanes or lamellae. All three lamella have striations when viewed in a longitudinal section and these striations are perpendicular to the "9+2" axoneme.
